However, for those of you living in the great white north and actually fly during the winter, one other item is worth considering. Snow and Ice removal from the door. We were fortunate to get a south facing hangar (door on south side) so that the sun helps melt the snow and ice at the bottom of the door. I've had hangar space on the north side and can tell you that the extra work to get the doors open during the winter was incredible and was sufficient to make me not fly on many occasions. I'm very glad indeed for the south facing hangar, even though our prevailing winds are from the SW and average wind speed here in the winter is 14 mph.... only 9 mph in August.

Inertia 2800 kg cm >> Rick - Thanks for the data on prop inertia. As we see from your post, Powerfin props have the lowest rotational inertias compared to most (all?) the other props. This is one of their selling points - low inertia provides less stress on the engine & gearbox. However, this can also be a negative. For example, I had used a Powerfin on the Verner engine that was originally installed in my Mark-III. It was too light. Result was insufficient "flywheel effect" for this engine, and it was not damping out the engine power pulses sufficiently, causing the prop redrive hub bolts to break.

Shouldn't be that hard if you use a hammer drill. You can rent one and even the bits from most industrial rental places. If your intent is only to keep it from moving you shouldn't need that much being sheltered by the hangar itself. They could screw in and out of the floor. jerb At 01:10 PM 12/19/2006, you wrote: > >You want the hangar to take the wind, not the aircraft inside so I would >put the doors 90 degrees to the wind.

That kind of strength wouldn't be needed very often.

It'd be interesting to see some comparative tests of various concrete anchors. I've worked with quite a few over the years, and some that I've seen work OK in shear, but poorly in tension. Then again, some I've used that have a tapered lower section that pulls up into an expandable sleeve are perty husky. Some have impressed me quite a bit, and I'd be hard put to picture one pulling out. That, of course, would depend to some extent on the concrete itself. On that, I've seen some home mixed and poured stuff that wasn't much better than putty. Others have been like granite, so ya never know. Lar.

According to one part of their website, they say their engines are NOT for aircraft use, on another page they say they're used for light aircraft and PPC's, and in still another (dated 2003) they say they want to sell the aircraft engine business. I'm guessing it's just a liability CYA thing? Not that I need any parts at the moment for the Cuyuna on my Ultrastar, but it's nice to know what the deal is. On a sorta related note, what about the Simonini Victor 1 engine? Single cylinder, dual ignition, water cooled, 48hp and 70 lbs with accessories... seems perfect for an Ultrastar or similar. Dunno what it costs though... there's also their 33hp Mini 2 which weighs only 44 lbs. The Mini 2 (28hp) is quite popular on PPG's these days. -Dana -- -- Why is it that doctors call what they do "practice"? ________________________________ Message 11 ____________________________________ Time: 07:05:17 PM PST US From: Russ Kinne Subject: Re: Kolb-List: Hanger location LAR, YOUR WIDESPREAD KNOWLEDGE NEVER FAILS TO IMPRESS ME (sorry, hit CaPS KEY) Thanx for sharing with us.
